I was diagnosed at age 37 or so with hypothyroid, by my GYN of all things. He had done some bloodwork as it hadn't been done in awhile at his office and noticed that my bad cholesterol was high, at this time I was strictly on a regimented weight loss and he said he found it hard to believe my cholesterol was high. He did a thyroid profile and levels were off. Once the thyroid was back to normal range, my cholesterol levels came back to normal levels also. He said he's diagnosed several hypothyroids by the cholesterol level..good thing, my drs office hadn't been telling me the results of my blood for the last 2 years, figured no news was good news. Needless to say, a new primary dr was in order.
